I am a new owner of my Line 6 HD500 and really excited about this gear. It has been a challenge at times to learn all its features & what it has to offer. I recently added some custom mod tones that now I am not happy with. My Question is : How do I remove some of them ? Have a great Day & Rock & Roll.

There's really no delete function for the presets, but you can overwrite them with anything you want. If you want to overwrite them with on of the blank presets, you can copy and paste using HD Edit, or on the HD500 itself you can hit the save button while in the preset you want to save and then choose the location you want to overwrite.
